1.選擇檔案夾路徑傳遞到textbox中
2.遍歷檔案夾所有檔案
3.如果combox選擇.txt或者.xls
則獲取所有后綴為.txt或者.xls
4.獲取textbox2中從鍵盤輸入的文本
從獲取的所有.txt或者.xls文本中篩選出所在文本并輸出打開文本
uj5u.com熱心網友回復：
需求定的很明確啊 一步一步寫唄 先建個表單程式 然后 有textbox textbox2 還有一個Combobox再加幾個測驗按鈕 。。。。一步一步寫 遇見不知道 按照要求百度 這個東西不難uj5u.com熱心網友回復：
得學下下相關知識點，控制元件集，Directory/FileStream,比較麻煩的時最后一個描述功能。uj5u.com熱心網友回復：
基礎沒學好，最后判斷的不知道從哪里下手
uj5u.com熱心網友回復：
你這是要交作業嗎uj5u.com熱心網友回復：
是的，感覺不知道怎么下手

最后一個判斷洗掉所以檔案的想不通，用的if
uj5u.com熱心網友回復：
是的，選擇檔案后綴的都可以洗掉，只有判斷洗掉所以的，洗掉不了

好的，有些方面還是學習的少，不是太懂
